O.D.M.S. device (Optical Density Measurement System) has been designed and manufactured in order to measure the turbidity of liquid products in transparent containers.
The system works using a non-invasive measurement method, suitable for turbidity analysis in ampoules, pre-filled syringes, cartridges and vials.
The optical density measuring unit is composed of a laser module, a sensor head and an embedded processing unit.
The inspection is performed by measuring the optical density of the solution in each container using a laser beam gun and a receiving photodiode sensor.
Colour is a vital source of information for molecules and materials in general. It intimately depends on molecular structure and a little variation in molecules shape or composition could change their spectroscopic properties. Oxidation, unwanted reactive contaminants in solution, thermal stress and UV degradation are some of the processes that could alter or damage a molecule.
The Spectrometer (Colour Analyzer) device measures a transmission spectrum for every analyzed container and compares it to a previously recorded reference one to detect possible product degradation and to implement anti-mix-up functions.
The inspection is performed by a dedicated station which can be easily integrated in Brevetti C.E.A. inspection machines.
